FFVII Rebirth - Red XIII vs Midgarsormr (Hard Mode, No Damage, No Limit)
I finally decided to try out Red XIII! I did some research on a build that works and I found one that works with some tinkering. I saw that Sidewinder is incredibly strong accompanied by Braver, Vengeance Mode and Dark Side (which I will not be using because it is a no damage run). So that is my main source of damage.
